JOHN A. MOMANUS, OF PHILADELPHIA, PENNSYLVANIA.

WAVE-MOTOR.

Specification of Letters Patent.

Patented June 12, 1906.

Application filed October 3, 1905. Serial Nc 281.108-

To all whom it may concern:

Be it known that I, JOHN A. MOMANUS, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Im rovement in Wave- Motors, of which the fol owing is a specification.

My invention relates to a new and useful improvement in wave-motors, and has for its object to so construct such an apparatus as to readily utilize the power in the Waves of the ocean to automatically ump Water to an elevated reservoir or supplg compressed air to a closed receptacle.

With these ends in view my invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which my invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by letter to the accompanying drawings, forming a part of this specification, in which Figure 1 is a plan view of a boat or float having my improved apparatus fitted thereto; Fig. 2, a side elevation of the same, and Fig. 3 a cross-section showing a slightly modifled form of my invention.

In the drawin s A represents a float which may be in any form desiredsuch as a flat barge or inclosed boatand B and B are two cylinders secured to the float in line with each other having a piston-rod C, which passes into each of the cylinders and connects with a suitable piston D therein. Feedpipes E and E connect the cylinders with the water u on which the boat is floating, and a pipe F eads from each of the cylinders to a eXible pi e or hose G, the latter leading to any suitab Ie reservoir on land.

H is a weight secured upon the piston-rod C, and I represents truck-wheels j ournaled to the weight and traveling upon the tracks J, secured upon the boat.

In practice such an apparatus as just described is anchored at a suitable distance from the shore, so as to stand onto the waves, and the rising and falling of the waves will cause the boat to oscillate in such manner as to alternately raise and lower the op osite end thereof, and this oscillation will pro uce a to-and-fro movement of the truck-wheels I, the weight H serving to increase this to-andfro movement and to add force thereto. As

the weight moves with and fro, the piston within the cylinder will be moved back and forth to the piston-rod O, and thus draw in Water through the pipes E and E, and thus eXpel the same through the pipe F, it being understood that suitable valves are located in these pipes. The water thus forced from the cylinders may be conveyed through the flexible pipe G to an elevated tank or reservoir and thereafter be utilized to revolve a turbine or other wheel adapted to run all classes of machinery.

In Fig. 3 I have shown a slight modification of my improvement which consists in suspending a weight K on a rod L, pivoted at M to the boat, andconnecting this rod to the piston-rod N in such manner that the swing ing of the weight will cause the piston-rod to move back and forth, thereby producing the same results as above described.

In practice I have found that when the construction shown in Fig. 3 is used the wei ht K and rod L stand substantially vertica at all times, due to the resistance of the water against the weight when connecting with the quantity of the latter wheel, the oscillating of the boat causing the cylinders to move to and fro, the rod L thus permitting the water, as above set forth. If found desirable, suitable screens or sieves 0 may be placed over the feed-pipes to the cylinders, so as to protect them against drawing in seaweed or other substances which would clog the pump-cylinders. When it is desired to use my improvement for compressing air, the feed-pipe which leads to the cylinders would project upward so as to permit air to be drawn to the cylinders instead of water. It will be understood that any number of these apparatuses may be used to pump water or air to a single reservoir or tank, and while each apparatus may be pumping but a comparatively small amount the quantity conveyed to the reservoir or tank may be increased to the desired amount by adding the requisite number of apparatuses.

Having thus fully described my invention, what I claim as new and useful is 1. A wave-motor consisting of a float, two cylinders located thereon, a single piston-rod passin into each of these cylinders, a piston carrie at each end of the piston-rod, a feedpipe leading to each cylinder, a dischargepipe leading from each cylinder suitable check-valves located in these pipes, a flexible pipe leading from the discharge-pipe whereby the Water or air delivered from the cylinders may be conveyed to a suitable reservoir or tank upon land and a Weight adapted to move the piston-rod When the float is oscillated by 5 the Waves as specified.

27 A Wave-motor consisting of a suitable float, tWo cylinders secured thereon, a piston fitted to each cylinder, a piston-rod secured to and connecting the two pistons, a Weight 10 carried bythe piston-rod, truck-wheels sup porting said Weight, tracks upon Which said truck-Wheels are adapted to run, a feed-pipe leading to each of the cylinders, a dischargepipe connected with each of the cylinders, check-valves located in each of these pipes and a flexible pipe leading from the dischargepipe to a suitable reservoir or tank.

n testimony whereof I hereunto affix my signature in the presence of two subscribing Witnesses.
